Polynucleotides
Experience the transformative Polynucleotide — also known as Salmon DNA — treatments at Dr Rasha Clinic in Knightsbridge. This innovative skin-rejuvenation therapy harnesses purified, naturally-derived polymerised polynucleotides — key building blocks of DNA and RNA — to repair, hydrate and revitalise the skin from within.

What Are Polynucleotides / Salmon DNA?
Polynucleotides (often referred to as Salmon DNA in the aesthetics industry) are highly purified DNA fragments originally extracted from salmon, a natural source well-known for its powerful regenerative properties. When injected into the skin, these biocompatible molecules:

- Stimulate cellular regeneration and tissue repair
- Boost hydration by attracting and binding water molecules
- Improve skin elasticity and overall texture
- Promote collagen and fibroblast activity for long-term rejuvenation
The result is a smoother, firmer, and more radiant complexion — ideal for tired, dull or ageing skin.
Key Benefits
- Deep Skin Rejuvenation – Activates cellular renewal to restore vitality and elasticity.
- Improved Hydration – Retains moisture for plumper, more supple skin.
- Targeted Eye Rejuvenation – Effectively treats fine lines, puffiness and dark circles in the delicate eye area.
- Non-Invasive and Safe – Gentle, biocompatible formula suitable for all skin types.
- Enhanced Skin Quality – Reduces visible signs of ageing, improves tone and luminosity.
How It Works
Polynucleotide / Salmon DNA injections trigger the body’s natural repair mechanisms. Once administered into the dermis, they:
- Bind to water molecules, increasing hydration and firmness.
- Activate fibroblasts, encouraging collagen and elastin production.
- Scavenge free radicals, reducing oxidative stress and inflammation.
- Enhance microcirculation, delivering oxygen and nutrients to skin cells.
This process helps restore youthful structure, improves texture, and accelerates healing — particularly beneficial after laser, microneedling or RF treatments.
Treatment Areas
- Face and Neck
- Under-Eye Area
- Décolletage
- Hands
- Scalp (for improved hair vitality)
Expected Results
- Noticeable hydration and glow after the first session
- Progressive firmness and elasticity over several weeks
- Reduction in fine lines and improved skin tone after a full treatment course
Aftercare & Recovery
After Polynucleotide treatments, ensure lasting results with effective aftercare. Your practitioner will discuss personalised aftercare, but general recommendations include:
- Avoid Intense Exercise: Limit strenuous activities for 1-2 days post-treatment.
- Light Activity Only: Gentle movement can support circulation and ease any soreness.
- No Heat Exposure: Refrain from hot baths, saunas, or steam rooms for 1-2 days post-treatment.
- Avoid Anti-Inflammatory Medications: Allow natural healing by avoiding these immediately post-treatment.
